News story gives a number in area code 248, to be given out if you are asked for your telephone number by someone whom you are not interested in. The full telephone number is given in the story (let me know if I should send it along to you). Notice that at least some of you reading this, if you were given such number, would be able to figure out where it was (at least where the prefix is).
Story also says "Rejection Hotline" now serves 29 U.S. cities.[TELECOM Digest Editor's Note: By all means, Carl, please send along the number, or at least a link to the article you saw. PAT]
